Re: What am I doing wrong?

For this problem, find the critical points of this equation and drop the signs for the particular ranges.

In this case, it's when 2x+1 = 0 and x+3 = 0, so x= -1/2 and -3

When x< -3, 2x+1 is negative and so is x+3

Hence on the condition that x< -3, -(2x+1) < -(x+3) if and only if 2x+1 > x+3 if and only if x>2

Does there exist solutions with x<-3 and x>2?

Repeat the same process for intervals (-3,-1/2), (-1/2, positive infinity). When solving the inequality the possible solution set intersected the interval in which the inequality is valid, will give you your solution

First time post. Thought I posted in the wrong area.

If that's the case, you just report your post and tell them what happened, the mods will move it for you.
